Dear all,
I have a file and I am using a code-
df=read.table("Case2.pileup",fill=T,sep="\t",colClasses = "character")
to create a data frame that is df.
now in 4th column I have ASCII values which I want to convert in decimal
values.the data frame is like this-
V1 V2 V3 V4
9 2 ., a\
9 2 .$, a`
13 1 , a
13 1 , a
13 1 , a
13 1 , a
13 1 , `
13 1 , ^
13 1 , a
13 1 ,$ a
I am using this code to convert it-
as.numeric(charToRaw(df[,4]))
it is showing this error-
Warning message:
In charToRaw(df[, 4]) : argument should be a character vector of length 1
all but the first element will be ignored
and it is converting only the value in first row.How can I do this for all rows
in my data frame.
Please help me.I am new user for R.I will be very thankful to you.
Thanking you,
Warm Regards
